Job opportunities

Polarization measurements of the cosmic microwave background (CMB) are one of the most
exciting areas in observational cosmology, and dealing with astrophysical foregrounds to the
CMB is one of the major challenges in this area. We have an opportunity for a researcher to join
our team working on observation and analysis of foreground data, using current generation
instruments, and also to help plan for the next generation of experiments. Oxford is leading the
C-Band All-Sky Survey (C-BASS), which is a project to measure the brightness of the whole sky
in both temperature and polarization and is a collaboration also involving partners at
Manchester, Caltech and South Africa. C-BASS has already observed the entire northern sky at
5 GHz and is currently observing the southern sky. The successful candidate will join the team
in Oxford working on analysis of data from C-BASS and other CMB experiments. They will also
contribute to the design of NextBASS, which will observe over a broad range of microwave
frequencies, and be involved in multi-national CMB projects such as LiteBIRD.

Applications are invited for a Postdoctoral Research Assistant in Ocean and Climate Dynamics (Heat Uptake). The post is available initially for a fixed-term until 30 September 2021.

This project will focus on a new estimates and understanding of ocean heat content (OHC) changes.
The successful candidate will join the Climate & Ocean Physics Group led by Prof Zanna as part of the TICTOC project coordinated by Dr Elaine McDonagh (NOC). TICTOC includes six UK institutions and several international partners.

The postholder will develop a new understanding of ocean heat content (OHC) changes by developing new conceptual models and producing new estimates of OHC, splitting it into contributions from
excess energy in the climate system and from the redistribution by the ocean circulation using transient tracers and Green’s functions. The goal is to ultimately refine our theory and projections of 21st-century dynamic sea level change and ocean heat uptake.

Duties will also include reporting on results and progress including publication of papers and presentations at conferences, workshops etc. The postholder will also be expected to develop new ideas, maintain up to date knowledge of research in relevant areas and to actively contribute to the intellectual life of the dynamic research group. The postholder will have the opportunity to teach.

Applicants should possess, or be close to obtaining a doctorate in physical, mathematical, computational or engineering science or a related field. Previous experience in modelling of the ocean, atmosphere or a nonlinear system of comparable complexity will be an advantage. Candidates are expected to demonstrate strong physical insight and analytical ability, drive and ability to perform original research of international standing, as well as an understanding of essential physical oceanography and climate dynamics.

Please direct enquiries about the role to Prof Laure Zanna(laure.zanna@physics.ox.ac.uk)

Only applications received before midday (UK time) 14th May 2018 can be considered. You will be required to upload a CV with an up-to-date publication list, a brief statement of current research interests, a supporting statement and details of three referees as part of your online application.

Applications are invited for a Postdoctoral Research Assistant in Ocean and Climate Dynamics (Sea Level Projections. The post is available initially for a fixed-term until 30th September 2020.

This project will focus on understanding of projections of regional dynamic sea level rise.
The successful candidate will join the Climate & Ocean Physics Group led by Prof Zanna as part of the UKFAFMIP project coordinated by Prof Jonathan Gregory (Reading).

The Postdoctoral Researcher will contribute to identify, quantify and constrain the causes of the ocean model spread in sea level projections by using (and designing) novel ocean-only simulations and devising new analysis of the results. The Postdoctoral Research Assistant will help improve our understanding of key aspects of ocean climate change and their representation in models, especially interior heat transport and circulation change, offering the potential to refine projections.

Duties will also include reporting on results and progress including publication of papers and presentations at conferences, workshops etc. The postholder will also be expected to develop new ideas, maintain up to date knowledge of research in relevant areas and to actively contribute to the intellectual life of the dynamic research group. The postholder will have the opportunity to teach.

Applications are invited for a Senior Researcher in Exoplanet Climate Theory and Simulation. The post is available for a fixed-term duration until 30th September 2022.

The post holder will join the team of the European Research Council Advanced Grant Project EXOCONDENSE, under the direction of Raymond T. Pierrehumbert, Halley Professor of Physics. The goal of the project is to develop a comprehensive understanding of the effect of condensible substances on the climate dynamics of exoplanet atmospheres. In effect, the project seeks to generalize the range of processes familiar from moist climate dynamics on Earth (involving condensation of water vapor) to the much broader range of condensible substances, equations of state, and dynamical configurations that may be encountered in exoplanet atmospheres.

The successful candidate will carry out research in either the general area of three dimensional simulation of convection with phase change, parameterization (closure) models of generalized condensible convection or condensation effects in global circulation models, according to background and interest. Cloud formation processes are of interest in connection with any of these topics.

The work will consist of developing and interpreting simulations of relevant processes, plus development of the theoretical framework needed to understand the simulations. Identifying observational signatures amenable to testing by current or future observational programs is a central goal of the program. The post holder will have the opportunity to teach.

Applicants should possess a PhD/DPhil with post-qualification research experience or equivalent and ideally a strong background in planetary atmospheres and numerical simulation of fluids.
Previous experience with cloud processes, radiative transfer and either general circulation or convection modeling will be an advantage. A demonstrated ability to initiate and conduct independent research is essential, as is a high degree of experience with programming techniques for high performance computing.
